Introduction. Explanation of how to live as la Another factor that contributes to global warming is volcanic eruptions. A single volcanic eruption, for example, can release a significant amount of carbon dioxide and ash into the atmosphere.
Global warming - Simple English Wikipedia, the free encyclopedia
The global warming controversy concerns the public debate over whether global warming is occurring, how much has occurred in modern times, what has caused it, what its effects will be, whether any action can or should be taken to curb it, and if so what that action should be. In the scientific literaturethere is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases. As of [update] the U. National Oceanographic and Atmospheric Administration says the global yearly average temperature has been warming at rate of 0. The controversy is, by now, political rather than scientific: there is a scientific consensus that global warming is happening and is caused by human activity, essay on global warming wikipedia.
Political and popular debate concerning the existence and cause of global warming includes the reasons for the increase seen in the instrumental essay on global warming wikipedia recordwhether the warming trend exceeds normal climatic variations, and whether human activities have contributed significantly to it. Scientists have resolved these questions decisively in favor of the view that the current warming trend exists and is ongoing, that human activity is the cause, and that it is without precedent in at least years. Global warming remains an essay on global warming wikipedia of widespread political debate, often split along party political lines, especially in the United States.
The sources of funding for those involved with climate science opposing mainstream scientific positions have been questioned. There are debates about the best policy responses to the sciencetheir cost-effectiveness and their urgency. Climate scientists, especially in the United States, have reported government and oil-industry pressure to censor or suppress their work and hide scientific data, with directives not to discuss the subject in public communications. Legal cases essay on global warming wikipedia global warming, its effects, and measures to reduce it have reached American courts.
The fossil fuels lobby has been identified as overtly or covertly supporting efforts to undermine or discredit the scientific consensus on global warming. The theory that increases in greenhouse gases would lead to an increase in temperature was first proposed by the Swedish chemist Svante Arrhenius inbut climate change did not arise as a political issue until the s. It took many years for this particular issue to attract any type of popular attention. In the United Statesthe mass media devoted little coverage to global warming until the drought ofand James E.
Hansen 's testimony to the Senatewhich explicitly attributed "the abnormally hot weather plaguing our essay on global warming wikipedia to global warming. Global warming in the U. gained more attention after the release of the documentary An Inconvenient Truthfeaturing Al Gore. The British press also changed its coverage at the end offollowing a speech by Margaret Thatcher to the Royal Society advocating action against human-induced climate change. At the same time environmental organizations and the political opposition were demanding "solutions that contrasted with the government's". If a doctor sees a child with a fever, he can't wait for [endless] tests. He has to act on what is there. Many European countries took action to reduce greenhouse gas emissions before West Germany started to take action after the Green Party took seats in Parliament in the s.
All countries of the European Union ratified the Kyoto Protocol. Substantial activity by NGOs took place as well. In Europe, the notion of human influence on climate gained wide acceptance more rapidly than in the United States and other countries. Inthe BBC announced the cancellation of a planned television special Planet Reliefwhich would have highlighted the global warming issue and included a mass electrical switch-off. I think there are a lot of people who think that, but it must be stopped, essay on global warming wikipedia. The authors of the book Merchants of Doubtprovide essay on global warming wikipedia for the assertion that professional deniers essay on global warming wikipedia tried to sow seeds of doubt in public opinion in order to halt any meaningful social or political progress to reduce the impact of human carbon emissions.
The fact that only half of the American population believes global warming is caused by human activity could be seen as a victory for these deniers. A compendium of poll results on public perceptions about global warming is below. Ina report on public perceptions in the United Kingdom by Ipsos MORI [46] reported that. The Canadian science broadcaster and environmental activist David Suzuki reports that focus groups organized by the David Suzuki Foundation in showed that the public has a poor understanding of the science behind global warming, essay on global warming wikipedia. An example of the poor understanding is public confusion between global warming and ozone depletion or other environmental problems. But there is no evidence of alarm over global warming in either the United States or China —the two largest producers of greenhouse gases.
A nation poll by Pew Global Attitudes conducted infound, "Substantial majorities 25 of 37 countries say global warming is a 'very serious' problem. There are differences between the opinion of scientists and that of the general public. Many of the critics of the consensus view on global warming have disagreed, in whole or part, with the scientific consensus regarding other issues, particularly those relating to environmental risks, such as ozone depletionDDTand passive smoking, essay on global warming wikipedia. Mooney says that the promotion of doubt regarding issues that are politically, but not scientifically, controversial became increasingly prevalent under the George W. This is also the subject of a book by environmental lawyer Robert F.
Kennedy, Jr. titled Crimes Against Nature: How George W. Bush and Corporate Pals are Plundering the Country and Hijacking Our Democracy ISBN Another book on this topic is The Assault on Reason by former Vice President of the United States Al Gore. The Heat Is On by Ross Gelbspan chronicles how Congress tied climate change denial to attacks on the scientific bases for ozone depletion and asbestos removal, among other topics. Some critics of the scientific consensus on global warming have argued that these issues should not be linked and that reference to them constitutes an unjustified ad hominem attack. Inaccording to The New York Essay on global warming wikipedia and others, oil companies knew that burning oil and gas could cause global warming since the s but, nonetheless, funded deniers for years.
The findings that the climate has warmed in recent decades and that human activities are producing global climate change have been endorsed by every national science academy that has issued a statement on climate change, including the science academies of all of the major industrialized countries. Attribution of recent climate change discusses how global warming is attributed to anthropogenic greenhouse gases GHGs. Scientific consensus is normally achieved through communication at conferences, publication in the scientific literaturereplication reproducible results by othersand peer review.
In the case of global warming, many governmental reports, the media in many countries, and environmental groupshave stated that there is virtually unanimous scientific agreement that human-caused global warming is real and poses a serious concern. While much remains to be learned, the core phenomenon, essay on global warming wikipedia, scientific questions, essay on global warming wikipedia, and hypotheses have been examined thoroughly and have stood firm in the face of serious scientific debate and careful evaluation of alternative explanations. Such conclusions and theories are then regarded as settled facts. This is the case for the conclusions that the Earth system is warming and that much of this warming is very likely due to human activities.
Among opponents of the mainstream scientific assessment, some say that while there is agreement that humans do have an effect on climate, there is no universal agreement about the quantitative magnitude of anthropogenic global warming AGW relative to natural forcings and its harm-to-benefit ratio. Dennis T. Averya food policy analyst at the Hudson Institutewrote an article titled " Scientists Whose Research Contradicts Man-Made Global Warming Scares" [78] published inby the Heartland Institute. The list was immediately called into question for misunderstanding and distorting the conclusions of many of the named studies and citing outdated, flawed studies that had long been abandoned.
Many of the scientists included in the list demanded their names be removed. Those who don't agree, essay on global warming wikipedia, are, unfortunately—and this is hard to say without sounding elitist—mostly either not actually climate researchers or not very productive researchers. A study, published in the peer-reviewed journal Environmental Research Letters analyzed 11, abstracts from papers published essay on global warming wikipedia the peer-reviewed scientific literature between andidentified by searching the ISI Web of Science citation index engine for the text strings "global climate change" or "global warming".
The authors found that of the 11, abstracts, endorsed that consensus, took no position on it, 78 rejected the consensus, and 40 expressed uncertainty about it. Ina letter from 52 leading skeptics was published by the Committee for Skeptical Inquiry supporting the scientific consensus and asking the media to stop referring to deniers as "skeptics". The letter clarified the skeptical opinion on climate and denial: "As scientific skeptics, we are well aware of political efforts to undermine climate science by those who deny reality but do not engage in scientific research or consider evidence that their deeply held opinions are wrong. The most appropriate word to describe the behavior of those individuals is 'denial'.
Not all individuals who call themselves climate change skeptics are deniers. But virtually all deniers have falsely branded themselves as skeptics. By perpetrating this misnomer, journalists have granted undeserved credibility to those who reject science and scientific inquiry. The "standard" view of climate change has come to be defined by the reports of the IPCC, which is supported by many other science academies and scientific organizations. Insixteen of the world's national science academies made a joint statement on climate change, essay on global warming wikipedia, and gave their support for the IPCC. Opponents have generally attacked either the IPCC's processes, people [87] or the Synthesis and Executive summaries; the full reports attract less attention. Some of the controversy and criticism has originated from experts invited by the IPCC to submit reports or serve on its panels.
Christopher Landseaa hurricane researcher, said of "the part of the IPCC to which my expertise is relevant" that "I personally cannot in good faith continue to contribute to a process that I view as both being motivated by pre-conceived agendas and being scientifically unsound," [88] because of comments made at a press conference by Kevin Trenberth of which Landsea disapproved. Trenberth said "Landsea's comments were not correct"; [89] the IPCC replied "individual scientists can do what they wish in their own rights, as long as they are not saying anything on behalf of the IPCC" and offered to include Landsea in the review phase of the AR4.
commented "Both Landsea and Trenberth can and should feel vindicated the IPCC accurately reported the state of scientific understandings of tropical cyclones and climate change in its recent summary for policy makers. Inthe House of Lords Economics Committee wrote, "We have some concerns about the objectivity of the IPCC process, with some of its emissions scenarios and summary documentation apparently influenced by political considerations. Speaking to the difficulty of establishing scientific consensus on the precise extent of human action on climate change, John Christya contributing author, wrote:.
Contributing authors essentially are asked to contribute a little text at the beginning and to review the first two drafts. We have no control over editing decisions. Even less influence is granted the 2, or so reviewers. Thus, to say that contributing authors or 2, reviewers reached consensus on anything describes a situation that is not reality, essay on global warming wikipedia. On 10 Decembera report was released by the U. Senate Committee on Environment and Public Works Minority members, under the leadership of the Senate's most vocal global warming denier Jim Inhofe. The timing of the report coincided with the UN global warming conference in Poznań, Poland. It says it summarizes scientific dissent from the IPCC.
While some critics have argued that the IPCC overstates likely global warming, essay on global warming wikipedia, others have made the opposite criticism. David Biello, writing in the Scientific Americanargues that, because of the need to secure consensus among governmental representatives, the IPCC reports give conservative estimates of the likely extent and effects of global warming. Hansen argues that the IPCC's conservativeness seriously underestimates the risk of sea-level rise on the order of meters—enough to inundate many low-lying areas, such as the southern third of Florida. Pielke Sr. has essay on global warming wikipedia stated essay on global warming wikipedia are significantly altering the global climate, but in a variety of diverse ways beyond the radiative effect of carbon dioxide.
The IPCC assessments have been too conservative in recognizing the importance of these human climate forcings as they alter regional and global climate. Henderson-Sellers has collected comments from IPCC authors in a workshop revealing a number of concerns. She concluded, "Climate change research entered a new and different regime with the publication of the IPCC Fourth Assessment Report. There is no longer any question about 'whether' human activities are changing the climate; instead research must tackle the urgent questions of: 'how fast? Attribution of recent climate change discusses the evidence for recent global warming.
Nonetheless, one argument against global warming says that rising levels of carbon dioxide CO 2 and other greenhouse gases GHGs do not correlate with global warming.
